A conversation with him inspires and boosts one's own self.

Mathias Gruber


Entrepreneur, leading figure of the energy transition, passionate mountainbiker and father of twins.

He inspires. He motivates. He fills the audience with enthusiasm and encourages reflection. Walter feels confident that we can “electrify” the world with renewable energies. He demonstrates this every day anew as a successful entrepreneur leading a highly motivated team. As a visionary and passionate advocate of the energy transition, Walter illuminates the past, questions the status quo and – in his very unique and fascinating way – points out to solutions that seem immediately achievable and economically viable.

Walter thinks holistically, acts sustainably and sets himself clear goals. This is also reflected in his personal life story.

The big birthday livestream #neoomlive01 on Tuesday the 31.3. was a great success. Exactly one year to the day after the successful trademark registration of neoom, it was the perfect occasion for a look behind the scenes and an opportunity to get to know the people of the company.

#10minutes POdcast

Under the title #10minutes Walter creates a campaign around a video podcast, which, in light of the current corona crisis, deals with another major problem of our time – climate change. Because while in the case of Covid-19 we can only react, it is already 5 past 12, there is still the chance to act proactively in the fight against climate change.

Fueled by top athlete Lukas Kaufmann, Walter fulfilled himself another life goal: to complete a marathon before his 40s. Before that it was 365 days no alcohol and lose 13kg, because “to bring body and mind to the limit widens the horizon.”


The strategic partnership with the successful entrepreneur Johannes Weißengruber and the establishment of W & Kreisel GmbH marked an important milestone in the international expansion of the company.


Walter was invited from Solar.Future.Today, an association of the world’s most important influencers and characters of the energy transition, to participate in a discussion with Tony Seba (linkedin) and Heinz-Josef Fell (linkedin) in Abu Dhabi.


When he circumambulated Mount Kilimanjaro on his mountain bike, Walter developed a close relationship to Africa and it’s people. Back home, Walter decided to support the Karibu World Association – an NGO which runs orphanages in Africa and India and is closely working with the involving locals: “Each and every person on our planet, irrespective of origin, religion or gender, should get a chance for education and a life worth living”

Kreisel Systems

Due to the strong grow of his business, Walter restructured the company into a GmbH and established the division called KREISEL SYSTEMS as a cooperation partner of KREISEL ELECTRIC. The company demonstrated the potential of renewable energies in the stationary area with the development of AC chargers and innovative software solutions. In the same year, Walter and his team were assigned from KREISEL ELECTRIC to plan and implement the entire building concept of the
new high-tech research and development center. They developed a cutting-edge, self-sufficient and interconnected building automation system so that the building can run on power it generates by itself. The KREISEL ELECTRIC research and development center is one of the most innovative commercial buildings in Europe.


Another team success! In 2016, about 4,500 took part at the “MTB Salzkammergut Trophy”, one of the most challenging mountain bike competitions in Europe. Lukas Kaufmann, Alfred Schabauer and Walter were in the winner’s circle, reaching the phenomenal third place.


Together with Philipp Kreisel, Kurt Lengauer and Rajal Clemens, Walter became “Indoor Mountain Bike World Champion”. They started as a real outsider team, however, the team always followed their mutually agreed plans during the 24-hour race. 



During his MBA, Walter founded his company walterkreisel – HOMETEC and hired his first employee. The aim of his company was to provide other people with the same level of comfort and well-being as he and his family are enjoying in their home-based on renewable resources of course, with a minimal ecological footprint and lowest operational costs.


Walter decided to participate in a MBA program as a second education in 2011, which he graduated with “magna cum laude” in 2012. He enlarged and deepened his professional expertise with practical business knowledge.


Building and moving into his “intelligent home”, based on the model of Bill Gates. At that point of time, a smart home was absolutely innovative. Walter asked for support and help, but nobody was really able to assist him with his plans. So, he got it done on his own. With the fully automated, smart building, Walter was laying the foundation for his company’s future direction at the same time.


Hello twins! Walter became a father of Theo and Finn. In his talks and lectures, Walter always encourages his audience to look at the world through the curious eyes of children, to question objectives, to try things out and think differently.


While still an apprentice, he has set up his own department and succeeded in winning numerous awards with his innovative ideas for the joint family business. Walter’s ingenious Hi-Fi system in his first car was published and praised as “best practice” and a point of reference in numerous specialized media. The company grew significantly between 1996 and 2006 and RED ZAC Kreisel became well known across borders. In 2010, RED ZAC Kreisel received the AERA (Austrian Retailer Award), the most prestigious award in their industry, and was named as “Austria’s Best Specialist Retailer”.

What others say about him

Walter proactively rises to speak. And he is heard. He has a clear mission: to electrify the world – ideally, the whole one – with energy from renewable resources. On his way, he meets exciting and enriching personalities.
